This was slated for 2022 at one point. I’m very happy to see things leveling off with this recommendation by the W3C. As Jeremy Keith said in his comments about this event on HTML5 Doctor:
On the one hand, it doesn’t really matter whether HTML5 is W3C recommendation or not. After all, what really matters to developers is what they can use in browsers today. So, from that perspective, the way the WHATWG views HTML as a “Living Standard” makes a lot of sense. On the other hand, it’s awfully nice to have some stability in the ever-changing world of web standards and browsers. That’s where the W3C provides balance. They are the yin to the WHATWG’s yang. HTML5 reaching recommendation status provides a welcome punctuation in the ongoing story of the most important format ever created.
“the most important format ever created”
That sums it up.
